“At this point, there is no danger to the public and nothing significant to the environment that we found,’’ said Mary Nguyen Bright, a spokeswoman for the S.C. Department of Health and Environmental Control.

Bright said initial reports show the leaked material pooled on a concrete pad at the site.

Officials discovered the leak during a routine inspection of a low-level waste processing system. A NRC report said the spill occurred in a line where officials are preparing processed radioactive waste for release.

SCE&G officials said repairs are under way. SCE&G said the spill, which they identified Thursday and reported to federal regulators Friday, didn’t threaten anyone. The power company described the leak as “slightly contaminated’’ water in a low-level waste processing system.

“Initial investigations by DHEC and SCE&G found the situation to have no adverse effect to public safety, site personnel or plant equipment,’’ the company said in a statement. “SCE&G will continue to work with DHEC and the NRC on this matter.
